In this article, a simple PHP class is implemented to list all the files in the specified directory in a weighted structure. Friends who are interested can take a look.

List all the files in the specified directory in a tree structure. In this way, all the files in the directory will be clearly structured in front of you. You can know what files there are at a glance, which is very convenient.

Example,

<?
/**
 * 列出目录中所有文件
 * by 程序员之家 bbs.it-home.org
*/

#例子
$t = new TreeClimber( "asp" ); //新建物件,设置需要列出的目录:在此为asp目录
echo arrayValuesToString( $t->getFileList( $t->getPath() ), "<BR>\n" );

function arrayValuesToString( $ar, $nl="", $dolast=true ) {//调用函数
$str = "";
reset( $ar );
$size = sizeof( $ar );
$i = 1;
while( list( $k, $v ) = each( $ar ) ) {
if ( $dolast == false ) {
if ( $i < $size ) {
$str .= $ar[$k].$nl;
}
else {
$str .= $ar[$k];
}
}
else {
$str .= $ar[$k].$nl;
}
$i++;
}
return $str;
}

//类 TreeClimber
class TreeClimber {
var $path;
var $fileList = array();
function TreeClimber( $path = "." ) {
$this->path = $path;
}

# 存取路径
function getPath() { return $this->path; }
function setPath( $v ) { $this->path = $v; }

// 返回指定目录里的文件列表,如果没有指定目录,将使用当前目录
//如果不能打开目录(可能没权限或目录不存在,将返回为空
//以递归方式进行
function getFileList( $dirname=null, $returnDirs=false, $reset=true ) {
if ( $dirname == null ) { $dirname = $this->path; }
# else { $this->setPath( $dirname ); }
# dout( "Recursing into $dirname..." );
if ( $reset ) {
$this->fileList = array();
}
$dir = opendir( $dirname );
if ( ! $dir ) {
print( "<B><FONT COLOR=#FF0000>注意: TreeClimber.getFileList( $dirname ): 不能打开 $dirname!</FONT></B>" );
return null;
}
while( $file = readdir( $dir ) ) {
if ( ereg( "^\.$", $file ) || ereg( "^\.\.$", $file ) ) continue;
if ( is_dir( $dirname."/".$file ) ) {
$this->getFileList( $dirname."/".$file, $returnDirs, false );
if ( $returnDirs ) { $this->fileList[] = $dirname."/".$file;}
}
else { $this->fileList[] = $dirname."/".$file; }
}
sort( $this->fileList );
return $this->fileList;
}
}
?>
When you use the above PHP class, remember to test it in a directory with fewer files first to get a clear tree structure. Of course, you can also extend this class to achieve more powerful functions.
